Teddington Action Group (TAG) has launched legal action against the UK Airports Commission challenging its methods of public consultation over air quality issues associated with the proposed expansion of the Heathrow Airport.
The London-based group has alleged that there was a lack of proper engagement by the commission as the allotted time of three weeks was insufficient to respond to a technical document running into 200 pages.
The group said in a statement: "The lack of proper engagement by the Commission in relation to the latest air quality consultation is unacceptable and local people should be consulted in a meaningful way on an issue that impacts their health and well-being."
The group has also questioned the sincerity of the head of the Commission Howard Davies, who is set to become the chairman of the Royal Bank of Scotland (RBS), the banker for Heathrow and Gatwick airports.
The group wants another round of public consultation on air quality and resignation of Sir Howard from his position.
The Airports Commission is expected to submit its final recommendation about the expansion of UK airports in a few weeks time.
Three options currently under consideration include the building of a third runway at Heathrow, extending an existing runway at Heathrow and construction of a new second runway at Gatwick Airport.
